Title:
FERROMAGNETIC MATERIAL, MAGNETORESISTIVE ELEMENT, AND ELECTRONIC FUNCTION ELEMENT
Document Type and Number:
Japanese Patent JP2003163392
Kind Code:
A
Abstract:
To provide a magnetoresistive element which has larger magnetic sensitivity and its ferromagnetic material as to a magnetoresistive material laminated having a nonmagnetic layer sandwiched between ferromagnetic layers.
The magnetoresistive element is constituted by using the ferromagnetic material which is MnM (M is silicon, germanium, or tin or a combination of ≥2 kinds of them) whose crystal structure has a sphalerite type. More preferably, the ferromagnetic material consists principally of manganese and an M element (M is silicon, germanium, or tin or a combination of ≥2 kinds of them) and has ≥60% spin polarization rate.
